Inserting ground strips in the low impedance microstrip segment results in a high effective capacitance that makes the characteristic impedance lower. Therefore, the characteristic impedance of the microstrip line is mainly controlled by the signal strips and the inserted ground strips in coplanar manner. The concepts and characteristics of this modified resonator structure are described in detail. Practical applications for planar bandpass filters employing the features of this resonator structure are discussed and fabricated. Besides, additional cross coupling structure which produces a pair of transmission zeros near the passband is also introduced to improve the skirt characteristics. Both simulated and measured results are presented. Chi-Yang Chang 張志揚 2007 學位論文 ; thesis 103 zh-TW |
